BaseQiNinjaDrive Aluminum 256GB Storage Expansion Card for MacBook Air 13" and MacBook Pro 13"/15" (Non-Retina) (256GB)

OK, I've had this for about 4-5 months now and initially it was working perfectly in a 13" MacBook Air. Then problems started with no access to files etc. Formatting didn't help and eventually the drive couldn't be formatted but visible to the OS. After extensive online research on forums etc I read a comment about using an official format program for SD drives/cards. Never knew this existed but apparently some systems have trouble formatting the SD type memory correctly (you might lose memory, e.g. giving only 64gb not 128gb, etc.). I tested the official formatter about 10 days ago and the card, which couldn't be formatted by Mavericks, was recognized and formatted (slow as I wiped the card of data) and it's been stable. Luckily I had my most important files on Time Machine and could reload saved photos back onto the card without problems. Can't get the link to show up but if you google SD Card Formatter 4 the first site that comes up will take you to the download page where both PC and Mac versions are available. Good luck.

Works as expected

So far so good, I am still having a lot of problems with my Macbook memory it is at full capacity very quickly and there are some things I can't put on the memory.The product looks amazing on the Mac, you could believe it is an original piece and pretty smooth.I recommend it completely

My MacBook Air was running out of space so I decided to get this it was the right decision. It’s made it very easy to increase the capacity of my laptop and the fact that I don’t have to remove it makes it very good

After unpacking this expansion card, I inserted it into the Apple Air. Works perfectly! Shows up on the desktop, and allowed me to set back up jobs. I'm going to order more. And did I mention it looks like it came from the factory with this card installed?

As advertised - additional storage for MacBookPro

Been working great so far. I'm using it for all my media and play from it regularly with no perceivable issues (even high bitrate media seems fine) Looks great as well as you cannot tell you have it installed at all.

Probably good for backups but too slow for viewing photos. If you're hoping to use this to manage your photo library be aware that attempting to scroll through iphoto library will be sluggish. And we're talking about viewing the thumbnails not the full photos. You have pause every page length before moving another page length.

It keeps lot of folders
